Woden not loading anymore
by Lusa Nicolas June 18, 2015

June 18, 2015

Hi, it was a while that I wasn't updating the woden version that I am using in my project, so today I thought to give it a try and see if there was something new. And now I am not able to load woden anymore, what I get is the following error message: Error: Name not found: WithOpenGLAndExamples I am trying to load it into a fresh Pharo 4 image, but no way, it doesn't load. Here are the version and repository I am referring to when trying to load it: version: #jenkins; repository: 'http://smalltalkhub.com/mc/ronsaldo/Woden/main'. Does anyone know what's going on? Cheers, Nicolas

Corrupted image after refactoring in class hierarchy
by Hilaire June 18, 2015

June 18, 2015

Hello, I am facing again this situation, with Pharo3, when the image becomes corrupted (crash at instanciation of a refactored class in a hierarchy). This time I have a log, it looks like a problem in ClassModification. Hilaire -- Dr. Geo http://drgeo.eu http://google.com/+DrgeoEu

Monticello / OS deadlock ?
by Jose San Leandro June 18, 2015

June 18, 2015

Hi, In one of our projects we are using Pharo4. The image gets built by gradle, which loads the Metacello project. Sometimes, we see the build process hangs. It just don't progress. When adding local gitfiletree:// dependencies manually through Monticello after a while Pharo gets frozen. It's not always the same repository, it's not always the same number of repositories before it hangs. I launched the image with strace, and attached gdb to the frozen process. It turns out It's waiting for a lock that gets never released. The environment is a 64b Gentoo Linux with enough of everything (multiple monitors, multiple cores, enough RAM). I hope anybody could point me how to dig deeper into this. # gdb (gdb) attach [pid] [..] Reading symbols from /usr/lib32/libbz2.so.1...(no debugging symbols found)...done.

Grapher bug?
by Luc Fabresse June 17, 2015

June 17, 2015

Hi, The doc here [1] says: "Data points may be stacked, meaning that the index of the point in the collection is its X value." When I use the same example as in the doc but with labels and ticks: b := RTGrapher new. ds := RTStackedDataSet new. ds dotShape color: Color red. ds points: #(5 1 20 5). ds y: #yourself. b add: ds. b axisX noDecimal. b axisY noDecimal. b build. b view inspect it seems that y values are not aligned on x ones (i.e. I would expect the first red point to be 1@5). Is it a bug or did I misunderstood something? [image: Images intÃ©grÃ©es 2] [1] https://dl.dropboxusercontent.com/u/31543901/AgileVisualization/Grapher/020… Thanks, #Luc

June 17, 2015

Hi Guys, I believe the Ring metamodel has been proposed 4 or 5 years earlier. Is it acctually in use in the current pharo tools? which ones? I have been told that Martin has develloped a different model : Ficus What are the limitations that Martin tried to fixed?What can be further unhanced? Thanks. Abdou.

Modal dialogs come up in different layers?
by Stephan Eggermont June 16, 2015

June 16, 2015

What's the difference between a ColorSelectorDialogWindow and a TextEntryDialogWindow? I call them in the same way from a palette, but the color dialog comes up over the palette, and the person dialog below. Both palettes are in layer 20. The low layer number seems to interfere with modality. addColor | dialog | dialog := ColorSelectorDialogWindow new title: 'Choose color'; selectedColor: self color; setProperty: #morphicLayerNumber toValue: 18. self openModal: dialog. dialog cancelled ifFalse: [self addMorphBack: (ColorWell on: dialog selectedColor)] addPerson |dialog| dialog := TextEntryDialogWindow new textFont: UITheme current textFont; title: 'Add person'; text: 'The email address'; entryText: ''; setProperty: #morphicLayerNumer toValue: 18. self openModal: dialog. dialog ifNil: [ ^self ]. (dialog cancelled or: [dialog entryText isNil]) ifFalse: [self addMorphBack: (PersonWell on: dialog entryText)] Stephan

Pharo 4.0 MethodContext Fuel
by Johannes Rasche Kreuzberg June 16, 2015

June 16, 2015

/Hi there, I'm still migration some stuff to Pharo 4.0 and am aware of the fact that MethodContext was deprecated and Context has to be used instead I'm migrating objects from Pharo 3 using Fuel - that works fine - except if an object is an instantion of a class containing blockclosures any advice ? thanks in advance Johannes /

breaking infinite loop from saved image
by Peter UhnÃ¡k June 16, 2015

June 16, 2015

In moment of my utter brilliance I managed to save image without noticing that I have infinite loop running... So it obviously crashed and launching is quite problematic. I managed to recompile infringing method from a startup script, since it seems strangly that it has higher priority, however right after that garbage collection kicks in and due to (probably) massive accumulated stack it dies again...(it is a nice 875M image -_-) ~~~~~~~~~ Smalltalk stack dump: 0xff916d80 I SmalltalkImage>lowSpaceWatcher 0xb7674470: a(n) SmalltalkImage 0xf2ae8a2c s [] in SmalltalkImage>installLowSpaceWatcher 0xf2ab50e0 s [] in BlockClosure>newProcess stack page bytes 4096 available headroom 3300 minimum unused headroom 3524 (out of memory) ~~~~~~~~~ Is there some magic remedy for this? It seems that there is a small window between starting the image and it crashing where I can do some little things; I managed to file out the most critical package like this, however I don't know where else I was making changes (day-ish of work)... The loop itself is announcement-based, so maybe that's why there is some room for experimenting... Thanks, Peter

right-aligned Spec labels ?
by Hartmut June 16, 2015

June 16, 2015

how 2 right-align a label text in Spec ? I assigned a Text instance to a label with textAlignment rightFlush: self /labelKey/ label: (/key/ asText addAttribute: TextAlignment rightFlush). However, LabelModel ignores the TextAlignment. Can it be done? and how?
